JOHN FREDERICK LIEBENTRITT, OF BANKSTOWN, NEAR SYDNEY, NEW

SOUTH WALES, AUSTRALIA.

MULTIPLE PUMP.

Patented April 2, 1907.

To all, whom/it may concern.-

Be it known that'LJoHN FREDERICK LIE- BENTRIT'IV, of Cumberland Pottery, Bankstown, near Sydney, in the State of New South Wales and Commonwealth of Australia, pottery and tile manufacturer, have invented an Improved Multiple Pump, of which the following is a specification.

This invention relates to an improved multiple pump wherein a series of barrels are arranged circularly and the pistons are actuated by the revolution of a cross-bar or handles similarly to a Windlass around the geometric center of the circleof barrels and wherein the elasticity of a comparatively large body of air /is utilized to assist the power applied; but in order that this invention maybe clearly understood reference will now be made to the drawings herewith, in Which- Figure l is a plan ofthis improved multiple pump complete. Fig. 2 is a partial sectional plan of the same through the pump-barrels, showing also suction-valves and suction-orifice. Fig. 3 is a sectional central elevation,

. and Fig. 4 is an enlarged detail of the pump piston or plunger.

The pump-barrels 4 are arranged circularly within a casing or air-chamber 5, having a bottom 6 and a top 7, the whole being airtightly jointed. The top and bottom have, greferably, a stay bolt 8- between them.

ach barrel terminates at bottom in an airchamber 31, having a discharge clack or valve 9 opening into the air-chamber and a suction clack or valve 10 connected to the source of supply, say, by pipe or bend 32 to a box 33 and suction-pipe 34. In each barrel is a piston 11 with leathers 12, preferably at top and at bottom. The top part and bolt of this piston or plunger 11 is made in two halves, sweated together with a ring shrunk around the top and so firmly securing the head or'knuckle joint 13 of rod 14, connected, preferably, by a universal joint 15 to the actuatin plate or disk 16. This late is held by col ars 17 loosely on aspind e 18, whose lower end is the ball 19 of a universal joint made up on the two halves of a receivingboss 21, secured together by bolts 20 and bolting to the top 7 of the air-chamber 5.

. The spindle 18 extends u wardly into a flat portion 24, taking in a s 0t or kee er in the operating cross-bar 26. The s 0t 27 in said spindle 18 is adapted to be placed in juxtaposltion with one or other of a series of bolt-holes in the keeper 25, and to thus en' able the spindle 18 and the disk 16 to be fixed in the desired inclined position or to be fixed normally out of operative position. The cross-bar 26 has fixed thereon rollers or runners 28 on the superimposed annular rail 29, supported by legs or standards 23 from the air-chamber top 7, and it has operatin extensions or handles30 outwardly of said runners 28.

In operation men or draft-animals walk around the multiple pump pushing or pulling the handles 30, and so causing the cross-bar 26 to revolve around its center, which is in line with the center of the circle in which the barrels 4 are arranged. When the spindle 18 is in the same center line, said disk 16, and consequently the pumps, are not operated. When, however, the spindle 18 is inclined, as shown in Fig. 3, it has motion upon its ball 19, around the center of said ball. The disk 16 is held free to revolve on spindle 18 between the collars 17 and is assisted by antifriction-rollers 22. Said disks 16 dips and rises in turn at every point in its circumference. By utilizing other of the bolt-holes in the keeper 25 the extent ofi this clip and rise may be adjusted, and consequently' the stroke of the pump-pistons be regulated. As this actuating-disk 16 dips and rises the pistons 11 are each in turn reciprocated in the barrels 4, causing the nec- 5, in which becomes imprisoned a large body of air whosev elasticity is thus utilized to give evenness of discharge through the general exit or discharge pipe 35 and to assistin the working of the pump.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- 1. A multiple pump comprising a circularseries of pump-barrels, pistons operating in the barrels, an inclined ,spindle, an inclined disk mounted on the spindle and connected with the pistons, a rotary operating device eccentric'ally connected with the spindle, and means for adjusting the spindle to change the inclination thereof.

2. A multiple pump embodying a circular series of pump-barrels, pistons operating in the barrels, an inclined spindle, an actuating disk or plate mounted on the spindle and connected with the pistons, and a rotary operating device, said spindle being adjustably connected with the operating device and movable toward and from the center thereof, whereby the inclination of the spin- -dle is changed.

3. A multiple pump embodying a casing, a plurality of pumpbarrels pistons operating in the barrels, a superimposed annular track, a rotary operating device mounted on the track, an inclined spindle eccentrically connected with the rotary operating device, and an inclined disk or plate mounted. on the spindle and connected with the pistons.

4. A multiple pump comprising a plurality of pump-barrels, pistons operating in the barrels, a superimposed annular track, an oper- 2o cross-bar and movable toward and from the 25 center to change its inclination, and a plate or disk mounted on the spindle and con-- nected with the pistons. In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
